BACKGROUND

The disclosed subject matter is in the field of mattress covers and bedding. More specifically, the disclosed subject matter features bed sheets with adjustable components and elements to improve the efficiency of dressing a mattress and securing the integrity of the bed sheet when on a mattress.

Mattress coverings and sheets are essential components for providing a comfortable sleeping environment and they also provide protection for both the mattress and user. Mattress decor is also a central and key aspect of a bedroom. Significant funds and societal value are invested in the aesthetic task of arranging a sheet on the bed.

Mattresses come in a variety of sizes, and, therefore, many types of mattress coverings covering a variety of dimensions have been designed to accommodate the various mattress sizes. The introduction of supplemental mattress pads have only added to the field of possible mattress dimensions. As a result, mattress coverings have to be purchased to fit each respective mattress size separately.

Furthermore, conventional bed sheets may rip apart or tear in the middle of the sheet due to stretching and fatigue. Additionally, the stitching or fabric around the edges and corners may also rip or tear due to wear and tear after repeated pulling and tugging from putting sheets on a bed.

Also, in some households, people have plastic mattress protectors over their mattresses, which results in a traditional bed sheet slipping off of the mattress.

Covering a mattress can be a time consuming and labor intensive project, especially for professions that require repetitive stripping and recovering of mattresses. Additionally, many people do not enjoy making a bed because of the frustrations that come with trying to put a bed sheet on a bed. Furthermore, studies have shown that prolonged leaning during bed-making leads to musculoskeletal disorders. (See Silva J S Jr., et. al., Evaluation of Lumbar Overload in Hotel Maids, US National Institutes of Health (2012).

In addition to the time and effort it takes to make a bed, current bed sheets can often come undone/untucked from the mattress when a user moves on top of the bed sheet, thereby causing the sheet to be tugged and pulled out from under the mattress.

Therefore, a need exists for an efficient and adjustable mattress covering system. A need also exists to stop the sheet from being pulled out from under the mattress by reason of user movement on top of the sheet when on the mattress. Accordingly, a solution may be sought for an easier and more efficient process of dressing a mattress with a bed sheet. Further, it is also desired for the bed sheet to better stay on the mattress when a user moves around on top of the sheet.

SUMMARY

The instant disclosure discusses coverings for a mattress that improve the efficiency of putting the coverings on the mattress. Hereinafter, the term “mattress covering” may interchangeably refer to a “bed sheet” and vice versa. Moreover, the term “bed sheet” may naturally include fitted or flat sheets.

The instant disclosure discusses a mattress covering that may include elastic members sewn into the top edge and corners of the mattress covering. The elastic members permit flexibility and stretching of the mattress covering. The elastic members may also prevent the mattress covering from ripping or tearing in the middle or along the edges and corners, which may occur from repeated tugging and pulling of the mattress covering. An advantage of the subject matter of the instant disclosure may be to maintain the integrity of the fitted mattress covering once spread over a mattress and to allow for more efficient mattress dressing. Another advantage of the subject matter of the instant disclosure may be to prevent the fabric or stitching on bed sheets from ripping or tearing in the middle or around the edges and corners of the bed sheet.

The instant disclosure also contemplates a flat sheet that may be used as a blanket.

The instant disclosure also contemplates a flat sheet that looks like a bed cover when a portion of the flat sheet is untucked from the mattress.

The instant disclosure also contemplates a bed sheet that may not slip off when there is a plastic mattress protector under the bed sheet.

The instant disclosure also contemplates a bed sheet that may include parallel drawstrings extending along the length of the bed sheet. Pulling the drawstrings may cause a progressive gathering of the bed sheet's distal end, resulting in a shortened and gathered coverage of the bed sheet over a portion of the mattress. Thus, the user may adjust the length of the bed sheet via the drawstrings. Further, the drawstrings may be tied together to secure the adjusted bed sheet at a desired length. The bed sheet may also include stitched corners on the distal end of the bed sheet to permit the securement of the distal end of the bed sheet to the mattress through enveloping and gripping the end surface of the mattress. Once secured to the end of the mattress, the remaining portion of the bed sheet may be pulled longitudinally to cover the top surface of the mattress.

The instant disclosure also contemplates additional fabric covering the stitched distal corners of the bed sheet. In one embodiment, the bed sheet covers the top surface of the mattress, while the additional fabric (sewn into the distal end of the bed sheet) lays over the distal end of the mattress covering the side of the mattress, as well as the stitched corners, thereby providing a more complete and aesthetically pleasing mattress covering presentation. The length of the additional fabric permits the fabric to be tucked underneath the mattress.

The instant disclosure also contemplates a slit in the bed sheet, configured to allow air to escape from the space between the mattress and the sheet when applied to the bed.

The instant disclosure also contemplates an apparatus that attempts to minimize user time expenditure and effort in dressing a mattress.

DETAILED DESCRIPTION OF THE DRAWINGS

Generally disclosed is a bed sheet that allows for adjustable, easy, and efficient application of a bed sheet to a mattress and with a mechanism that allows for movement of the sheet without it coming undone from the mattress. FIG. 1 is a perspective view of one embodiment of the bed sheet 100. Referring to FIG. 1, in one embodiment, the bed sheet 100 may be a fitted sheet with stretchable material sewn into the edges 300 and corners 200 of the bed sheet 100. Like a generic fitted sheet, the bed sheet 100 may also feature elastic along the perimeter of the bottom of the bed sheet 100 to fit under the bottom of a mattress. The stretchable edge 300 and corner 200 may be composed of a stretchable material, such as lycra, spandex, elastane, elastic, or other stretch fabric. The stretchable edge 300 and corner 200 allow a user to move around on the bed and pull and tug the material on the top of the mattress without pulling portions of the bed sheet 100 out from under the mattress. That is, the stretchable edges 300 and corners 200 allow the portion of the bed sheet 100 on top of the mattress to move without interfering with the integrity of the sides and corner of the bed sheet that keep it secure on the mattress.

FIG. 2 is a partial detailed view of the corner 200 of the bed sheet 100. Referring to FIG. 2, the “T” or “Y” shaped formation of the stretchable corners 200 and edges 300 are configured to allow for easy application of the bed sheet 100 on a mattress because when a user puts a sheet on mattress, he or she generally starts by slipping the sheet under one corner of the mattress as an anchor point and applying the remainder of the sheet by pulling and tugging the sheet from the secured corner and tucking in the remainder of the bed sheet 100 under the remaining corners and edges of the mattress.

FIGS. 3 and 4 are perspective views of one embodiment of the bed sheet 100. Referring to FIGS. 3 and 4, the bed sheet 100 is shown as a flat sheet that features side flaps 500 which hang down from the edge of the mattress along the length of the bed sheet 100. In an alternative embodiment, the side flaps 500 may hang down from three sides of the bed sheet 100. Referring to FIG. 4, the bed sheet 100 may be a flat sheet and feature an end flap 510 sewn into the end of the bed sheet 100 so that it wraps around and extends past a portion of the bottom two corners of the mattress. This allows for the end flap 510 to “catch” onto the end of the mattress and allow the user to easily pull the bed sheet 100 across the remainder of the mattress. That is, this end flap 510 allows for an easier and more efficient application of a flat sheet to a mattress because the end flaps 510 may be placed over the bottom of the mattress and then the bed sheet 100 is pulled in the opposite direction until the end flaps 510 catch against the corners and bottom of the mattress, wherein the bed sheet 100 becomes taut. Once the bed sheet 100 is taut, the side flaps 500 may be tucked in and under the remaining sides of the mattress. In an alternative embodiment, the bed sheet 100 has both ends defined by the end flap 510 and it may be used as a bottom flat sheet that is placed beneath another bed sheet 100 with only one end flap 510.

FIGS. 1, 2 and 8 show the stretchable corner 200. In one embodiment, the stretchable corner 200 anchors the bed sheet 100 through catching and attaching to the edges of a mattress in a hooking fashion. Once anchored around the mattress edge, the bed sheet 100 may be pulled flat along the top length of the mattress covering it entirely.

Still referring to FIGS. 3 and 4, the bed sheet 100 may feature a drawstring 400, wherein the drawstring 400 extends along the length of the bed sheet 100. In another embodiment, the drawstring 400 may extend only along a portion of the length of the bed sheet 100, for example, the drawstring 400 may extend along half the length of the bed sheet 100 or along a third of the length of the bed sheet 100. In an embodiment, the drawstring 400 is positioned on the bed sheet 100 wherein it is several inches inside of the edge of the mattress. That is, there is a portion of space between the drawstring 400 and the edge of the bed sheet 100 when it is on the mattress.

Still referring to FIG. 4, in an embodiment, the stretchable edge 300 only extends along the length of end flap 510.

FIG. 5 is a partial detailed view of the end of one embodiment of the bed sheet 100. Referring to FIG. 5, in one embodiment, the bed sheet 100 may feature a slit 600. The slit 600 allows air to escape from the under the bed sheet 100 when applied to a mattress. Frequently, there is an air bubble that is created when a bed sheet 100 is put onto a mattress, so the slit 600 allows for air to escape more quickly and allows a user to push air out of the slit 600. In an alternative embodiment, the slit 600 may be used to access a plug for an air mattress, permitting attachment of an air pump without having to strip the coverings off the mattress.

FIG. 6 is a perspective view of the drawstring 400 pulled, wherein the length of the sheet is shortened and the material of the bed sheet 100 is gathered. FIG. 7 is a partial detailed view of the drawstring 400. Referring to FIG. 7, the bed sheet 100 features a drawstring cavity 410, wherein the drawstring 400 is sewn into one end and housed. Referring to FIG. 7, there is also shown a tie-off string 420 sewn into the drawstring cavity 410, which allows a user to tie a knot with the drawstring 400 and the tie-off string 420 to secure the drawstring 400 in place and secure the adjusted length of the bed sheet 100 in place. Referring to FIGS. 3, 4, 6, and 7, in use, if a user wants to shorten the length of the bed sheet 100, the user may grab the tie-off string 420 or a portion of the bed sheet 100 and pull the drawstring 400, which will cause the bed sheet 100 to gather and shorten (see FIG. 6). In one embodiment, the bed sheet 100 may feature just the drawstring cavity 410, drawstring 400, and tie-off string 420. In an alternative embodiment, the bed sheet 100 may only feature the stretchable edge 300, at least one end flap 510, and at least one side flap 500.

FIG. 8 is a partial detailed view of one embodiment of the bed sheet 100 with the stretchable corners 200 and edges 300.

FIG. 9 is a perspective view of the end of one embodiment of the bed sheet 100.

In an embodiment, the bed sheet 100 completely encompasses the mattress with the stretchable corners 200 and stretchable edging 300 extending between the panels of the bed sheet 100.

FIGS. 3, 4 and 6 show the bed sheet 100 side flaps 500. In one embodiment, the side flaps 500 may be laid across a mattress edge covering the edge. In another embodiment, the side flaps 500 may be tucked underneath the mattress for a different aesthetic appearance.

In one embodiment, the bed sheet 100 may be 90 inches in width and 87 inches in length. In an alternative embodiment, the bed sheet may be 108 inches in width and 102 inches in length, wherein the end flap may be 14 inches in length. In an alternative embodiment, the bed sheet 100 may be 81 inches in width and 96 inches in length. In another embodiment, the bed sheet 100 may be 66 inches in width and 96 inches in length. In an embodiment, the stretchable edge may be 4 inches in height and is sewn into the edges of the bed sheet 100. In an embodiment, the stretchable corner is 4 inches in width and sewn into the corners of the bed sheet 100.

In an embodiment, the bed sheet 100 may be a fitted sheet, wherein the bottom elastic that wraps under the mattress and secures the bed sheet 100 on a mattress is in a range from one to three and a half inches (1″-3½″). This allows for a more taut fit around the mattress, wherein the bed sheet 100 exhibits less gathering and ruffling around the sides of the mattress. That is, the wider elastic provides a more secure and taut fit.

The bed sheet 100 may facilitate a more efficient process of making a bed and putting a bed sheet on a mattress because of the unique configuration of end flaps 510, side flaps 500, and stretchable edge 300. As a result, the bed sheet 100 may cut the amount of time to make a bed in half. That is, it may take 8-10 minutes to make a bed with traditional sheets, but with a bed sheet 100 as disclosed herein, it may reduce the time to make a bed to 3-4 minutes. In the hospitality industry, this allows hotels to make beds more quickly and more efficiently, thereby, saving time and money.
